Introduction 1
1. Introduction
The Model 214D-1 Batch Controller accepts pulse or frequency flow
signals and automatically controls the batching of fluids via a one or
two stage control valve.
The instrument is extremely flexible and easy to operate, with a four
key front panel operation that enables the batch quantity to be set and
batches to be started or stopped.
This manual covers the Model 214D-1 which accepts most frequency
and pulse signals, including mV outputs from turbine flowmeters, and 2
wire proximity switch outputs. It also allows all four front panel
switches to be remotely connected via the rear panel terminal strip.
The instrument is fully configurable, with all calculation constants set
via the front panel switches and stored permanently in a non-volatile
memory.
This instrument conforms to the EMC-Directive of the Council of
European Communities 89/336/EEC and the following standards:
Generic Emission Standard EN 50081-1 Residential, Commercial &
Light Industry Environment.
Generic Emission Standard EN 50081-2 Industrial Environment.
Generic Immunity Standard EN 50082-1 Residential, Commercial &
Light Industry Environment.
Generic Immunity Standard EN 50082-2 Industrial Environment.
In order to comply with these standards, the wiring instructions in
Section 7 must be followed.

Operation 5
3. Operation
The Model 214D-1 uses a low power CMOS microprocessor to
perform all control functions and calculations.
The instrument is fully configurable with all operating parameters and
calculation constants user settable. (See Section 5 entitled
"Configuration" for information on configuring.) All parameters and
constants are stored in a non-volatile memory which retains data
without battery backup for a minimum of 10 years.
A block diagram of the instrument is shown below.

increment the digit. The up arrow on the
3.1 Front Panel Operation
The four key operation makes the operation of the Batch Controller
very easy.
3.1.1 Setting the Batch Quantity
The batch quantity is set as follows:
Switch Action Display Comments
Press BATCH SET Batch "Batch" is displayed for one second
followed by the batch quantity last
entered. The Batch Set LED lights.
"1" 2345 The most significant digit flashes
indicating that it can be changed.
Press r "2" 2345 Pressing the DISPLAY key will
DISPLAY key indicates to increment
digit.
Press w 2 "2" 345 Pressing the RUN key will change digit
and enable the next digit to be
incremented. The right arrow on the
RUN key indicates to change digit.
Press BATCH SET Set Once the desired number is entered,
Once set, the batch quantity will be retained in the non-volatile memory
and will not alter until changed by the user.
The batch quantity can only be set while the instrument is in nonoperational state such as when the batch is complete or if the batch
process has been interrupted. However, the Batch key can be pressed
while in the run state and the batch quantity displayed. All digits will
flash to signal the quantity cannot be changed.
HP289
press the BATCH SET key to return to
the Run mode. The Batch Set LED will
extinguish.
Operation 7
3.1.2 Starting a Batch
To start the process the RUN key is pressed. The Run LED will light
and the instrument will begin to totalize from zero or, if programmed to
count down, the display will decrement from the batch quantity.
The batcher has two control relays which are energized and deenergized as described in Section 3.2.
3.1.3 Stopping
The process can be stopped at any time by pressing the STOP key.
Once the process has been interrupted in this way, it can be continued
by pressing the RUN key or the process can be aborted and the
instrument reset by pressing the STOP key a second time.
When the process is interrupted, the STOP LED will flash to prompt
the operator to either restart or abort the batch.
3.1.4 Resetting
The instrument can be configured to reset in one of two ways.
• At the end of a batch, the STOP key must be pressed to reset
the Batch Total. If the instrument is configured to count
down, the Batch Total will then reset to the preset quantity. If
it is configured to count up, the Batch Total will clear to zero.
• If Auto Reset is configured on, the Batch Total will
automatically reset when the RUN key is pressed to start the
next batch.
3.1.5 Displayed Information
The display will normally show the Batch Total which is the total count
for the current batch and is reset on each new batch.
The DISPLAY key can be used to display the following additional
information:
Rate
On the first press of the DISPLAY key, the display shows RATE
for one second followed by the flowrate.
HP289
8 Operation
Accumulated Total
On the next press of the DISPLAY key, the display shows ACC
for one second followed by the accumulated total. The
Accumulated Total cannot be reset during normal operation.
3.1.6 Limit on Batch Size
To prevent accidental entry of large batch quantities, a maximum batch
limit can be set during configuration. The operator is then prevented
from entering a batch quantity which exceeds this predetermined value.
HP289
Operation 9
3.2 Batch Operations
The Batch Control functions can be configured to operate in one of two
ways.
1. At the end of the batch, the STOP key must be pressed to reset
the Batch Total. (This must be done before another batch can
be started.)
HP289
10 Operation
2. If Automatic Reset is configured on, a new batch is
commenced each time the RUN key is pressed.
The Batch Controller can be configured to either count up from zero on
each batch or to count down from the preset batch quantity.
